On Friday, June 14th Santa Clara Valley Transportation Authority (VTA) held a historic ground breaking ceremony to mark the start of construction of its West Portal facility.

This is the site where the TBM will be assembled and launched to bore the 8 km (5-mile) underground tunnel for the BART Silicon Valley Phase II Extension Project (Phase II Project). This milestone event was held at the future Santa Clara Station and Newhall Yard & Maintenance Facility located in San José and Santa Clara, CA. 

VTA’s extension of the regional BART system is the largest transportation infrastructure project in the history of Santa Clara County. It will integrate Santa Clara County with the greater Bay Area BART system, enhancing regional connectivity and providing numerous economic, environmental, and social benefits. The Phase II Project is planned to begin passenger service in 2037.
